Billet 4 Description

Sleek lightweight, functional design.
CNC Machined from high quality 6082t6 billet aluminum.
Hand built, finished, polished and pressure tested in the UK.
Internal fluid crossover eliminates the need for external loop pipe.
Ideal for the front of vehicles from up to approx. 1300kg with a power to weight up to 250bhp per tonne.
Hi Spec Road Calipers
Hi Spec road calipers are perfect for road use and occasional track use.
All of our road calipers, except our Ultralite range, come equipped with dust boots to keep dust, dirt and grime away from the piston seals.
The Hi Spec Billet 4 caliper is available in two different looks, the classic and the recessed. This makes no difference to performance but the recessed style is 1.8mm thicker (this can make a difference to a kit fitting in a wheel or not).
